Can anyone tell me what is the correct gap size for NGK - LFR6AIX-11 spark plugs on a e92 328i with the n52 engine? I know that the gap size increases over mileage & this is my first time doing this on this car so measuring the current plugs is out the window. Thanks in advance!

They should be pre-gapped from the factory. You can check them to make sure they're all the same, but they recommend that you don't change the gap because the smaller electrode on iridium plugs can be easily damaged.

Thank you sir. Yes i wanted to check them since sometimes the gap isn't perfect
